Locational hedges project

Introduction

Locational price risk refers to unpredictable movements in the price for electricity at different node varies (locational prices) throughout the country. Locational prices are largely driven by transmission constraints that reflect many complex and uncertain aspects of the electricity system. Locational prices are also affected by transmission losses, which are more predictable.

Participants in the wholesale electricity market are currently limited in how they can manage locational price risk. In general, a purchaser's exposure to locational price risks depends on their volume of hedge contracts and level of self-generation (if any), and on where those contracts and generation units are located relative to the location of their load. Hedge contracts may not provide effective protection against this type of locational price risk.

The main source of locational price risk occurs between the two islands - inter-island locational price risk - which accounts for approximately two thirds of all locational price risk. The other third arises within each island-intra-island locational price risk.

Solutions are sought for both inter and intra island locational price risk which will provide participants with a mechanisms to manage their locational price risks.

Inter-island locational price risk

The Authority has notified a Code amendment in the Gazette, which allows for the introduction of financial transmission rights (FTRs).

The Code amendment comes into force on 1 October 2011, and the Authority intends for the FTR market to be operating from 1 October 2012.

Work on a solution to inter-island locational price risk has been ongoing since 2008; the introduction of financial transmission rights should help participants to manage this risk and increase retail competition.

Intra-island locational price risk

The Authority is also progressing a solution to intra-island locational price risk, and is currently identifying a list of high level options to be considered. High level options are being identified and will be discussed with the LPRTG before the end of 2011, with a view to forming an options paper for consultation in 2012. Further information will be added as the project develops.

Locational Price Risk Technical Group (LPRTG)

The LPRTG was established to provide specialist and technical advice in relation to the detailed design and operation of selected mechanisms for managing locational price risk.
